y GRUBBER;

Specification of Letters Patent.

Patented-May 14, 1907,

To a/ZZ whom t may concern.'

Be it known that I, DAVID TAYLOR, Jr., a citizen of the United States,and a resident of St. Francisville, in the parishof West Feliciana andState of Louisiana, have invented a new and Improved Grubber, of whichthe following is a full, clear, and exact description.

This invention relates to grubbers, and is particularly useful inconnection with devices of this character intended for use in removingrailroad ties and the like.

The object of the invention is to provide a grubber which is simple,strong and durable, and which is peculiarly adapted for use inconnection with hard, rocky ground or shale.

A further object olf' the invention is to provide a device of thecharacter described which may be used as a grubber, and which may alsobe used for removing the tie from underneath the rails after the samehas been freed from the earth or'ballast surrounding it.

A still further object of the invention is to provide a grubber whichmay be used as an ordinary crowbar as circumstances require.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly pointed out in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters oi reference indicatecorresponding parts in all the figures, in whichV Figure l shows aperspective view of a section of railroad track showing my invention lin operation Fig. 2 is a transverse section of a railroad track showingmy device in use for removing the tie; Fig. 3 is a side elevation of myinvention in -use for removing a post from the ground g Fig. 4 is asimilar view showing my invention in` use in a different manner forremoving a post; Fig. 5 is a side view showing an end of my device inlongitudinal section; and Fig. 6 is a perspective view of a detail of myinvention.

Referring more particularly to the drawings, I provide a lever bar 1,which may be of substantially rectangular section or of any suitableform. The upper end 2 of the bar is formed into a sharp point and has,near the point, a hook 3 rigidly mounted in a proper opening in the barand with its end riveted in I place. The bar, as wellasthe other partsofthe invention, may be formedy of steel or other material suitable forthe purpose. the opposite Vend of the bar which is given a slightlycurved form,is mountedaipointed blade or shovel 4, with the pointextending somewhat beyond the end of the ban The. end 5 of the barisbeveled and ta ered'to. a

of the shovel. The shovel is removablyattached to the bar by means ofscrew bolts `6 located in suitable openings in the-shovel and the bar.Attached rigidly upon the bar, near -the shovel and vsoIlflcWhat above.the same, is a hook 7 similar tothe hook-3 andattached in thesamemanner. I prefer to have the hooks 3 and 7 project.- from the barrespectively on opposite sides thereof.

the end which bears the shovel 4, is a stirrup 8 constitutinga removablebracket. The stirrup 8 has a flat face 9, and ends 10 inwardly disposedand separated a distance slightly greater than the diameter of the bar,

openings 11. ach' opening on one endv is substantially opposite toanopening onthe other end of the stirrup. A suitablehole is providedthrough the bar, and by meansofa bolt 12 passing through o positeopenings in the stirrup ends and the 'ole in the bar, the bracket ispivotally mounted upon the bar. A chain 13 is provided of suitablelength and having at one end a Hat hook 14, which is any other ancoring1 object, as shown most clearly in Fig. 2. T e chain is adapted tobe attached to either of the hooks upon the bar, and its links are ofsuch size that it may be attached to these hooks by meansofl one of itslinks, thus permitting any desired length to be secured by the operator.

In digging away the earth or ballast from around a tie, for the purposeof removing that tie, the mode of operation is, as follows.: The hook 14of the chain is caught u on-.the head of a rail and the point of the sovelvis placedat the whole length of t e chain from the rail to whichthe chain is anchored. On pulling at the upper end of the bar in adirection away from the rail to which the chain is anchored, the shovelwill be Jforced into the ground by the lever action of the bar7 ful-Removably mountedupon the bar, near.

said ends bein provided with a series of.

' fected with little physical exertion.

crumed by means of the chain'and the hook directly above the shovel.Vhen the shovel has penetrated` a certain distance into the groundthrough this leverage, the bracket 8 will rest against the ground andprevent further penetration, while, at the same time, providing a newfulcrum for the bar at that point. As the downward pressure upon the baris continued, the bar will pivot about this new fulcrum presented by thebracket 8, and the shovel will therefore, be forced upwardly from theearth, bringing with it a quantity of the same and breaking it up intofragments as the operation is repeated.

It will be understood that this invention is not intended for theremoval of the earth, but merely for the breaking up of the same intosmall parts. It is especially useful in Aconnection with ground which isparticularly hard packed, or containing stones and the like. By means ofthis device, great leverage may be exerted and the operation eflf theground is particularly hard the shovel 4 may be removed and the pointedend of the bar used to break up the ground.

Vhen the earth has been dug away from around the tie and it is desiredto pull the tie out from under the rails, the rail spikes are removed inthe usual manner, and the pointed end 2 of the bar is then driven intothe wooden tie, the chain 13 being attached to the hook 3, while thechain hook 14 is caught upon the rail head in the same manner as before.By pulling upon the shovel end of the bar away from the rail, theleverage about the hook 2, which acts as a fulcrum, will force the tiealong underneath the rail, and the operation may be repeated until thetie has been removed.

The bar l may be used for many purposes for which the ordinary crowbaris used at present, the pointed end making it particularly adaptable forthis.

The device may be used for pulling stumps, as shown in Fig. 3, the barbeing rested upon any suitable object to serve as a fulcrum, while thechain is secured about a post and attached to a hook upon the bar. Bypulling downward upon the end of the bar opposite to that which carriesthe chain, the leverage will tend to pull the stump upwardly out of theground. It may be used for the same purpose in a more simple manner bydriving the pointed end into the wooden post, using the hook as afulcrum by resting it upon the ground or on any suitable obj ect, andusing the bar as a lever in the ordinary manner.

The bracket 8 is adjustable by means of `the series of bolt holes in itsends, and the distance to which the shovel can penetrate the ground canbe regulated by increasing or decreasing the eiiective length of thebracket by inserting the bolt 12 through dill'erent openings 10 in thebracket 9.

Having thus described my invention, l. claim as new and desire to secureby Letters Patent:

1. A grubber, comprising a -bar having a shovel, means for removablyattaching said bar to an anchor, and a bracket pivotally mounted uponsaid. bar and adapted to rest upon the ground to act as a fulcrum forsaid bar.

2. A grubber, comprising a bar having a shovel, means for removablyattaching said bar to an anchor, and a bracket on said bar adapted tolimit the penetration of said shovel into the earth and to act as alulcruin for said bar.

3. A grubber, comprising a bar having a beveled, tapered end, a shovelremovably mounted near said end, means for removably attaching said barto an anchor, and a bracket on said bar having a i'lat face adapted torest upon the ground.

4. A grubber, comprising a bar with pointed ends, a shovel removablymounted upon said bar near an end thereof, a hook on said bar, a chainadapted to be removably attached to said hook, and means for anchoringsaid chain.

5. A grubber, comprising a bar with pointed ends, a shovel removablymounted upon said bar near an end thereof, a hook on said bar, ananchor, a chain adapted to join said hook with said anchor, and abracket adjustably mounted on said bar adapted to rest upon the groundwhen said shovel is driven thereinto.

6. A grubber, comprising a bar having pointed ends, a shovel removablymounted near an end of said bar, a stirrup ad justably mounted upon saidbar and constituting a bracket adapted to rest upon the ground, aplurality of hooks rigidly attached to said bar, and a chain having ananchoring hook and adapted to be removably attached to one of saidhooks.

In testimony whereof lf have signed my name to this specification in thepresence ol' two subscribing witnesses.
